PowerStream, a community-owned energy company, recently launched the first multi-standard DC fast charger in Ontario.

It’s located in Vaughan at PowerStream’s head office, just off Highway 400, and is free to use.

At 50 kW of power, charging shouldn’t take more than 30 minutes to 80% capacity (excluding Tesla).

ABB Terra 53 CJ is equipped with CHAdeMO plug and CCS Combo (North American version of course).

“The level 3 charging station’s power is being supplied by PowerStream but paid for courtesy of G&W Canada and Survalent Technology.”

PowerStream states that there are currently more than 2,000 electric vehicles in Ontario and approximately 300 in PowerStream’s service territory.

Maurizio Bevilacqua, PowerStream Board Chair and Mayor of the City of Vaughan commented:

“We are proud and excited to be working with Nissan, G&W and Survalent in bringing these new environmentally-friendly technologies to our customers. Launching the publicly-accessible level 3 charging station and introducing V2G technology serve as examples of why we continue to be recognized as an industry leader.”

Separately, PowerStream announced introduction of Vehicle-to-Grid (V2G) power supply system.

“PowerStream also today introduced the first commercial Vehicle-to-Grid (V2G) power supply system in North America with two high-capacity level 2 chargers connected to a solar carport located in the back parking lot of the company’s head office building.  PowerStream worked with Nissan to better understand how the all-electric LEAF can be connected to power systems to potentially benefit utility companies and drivers alike.”

    V2G and level 2? That would rule out any of the systems we’ve seen out of Japan using the DC port, and it would mean that they’ve got vehicles with onboard bidirectional chargers.

    1. Short answer is “no” as Level 2 standards are for charging only. See below (1) for more.

      “V2G” is an acronym that is in the hype phase of technology being defined. Depending on context V2G means different things.

      The phrase “Vehicle-to-Grid” (V2G) sounds like an PEV would be supplying power to the grid. The knowledge often omitted being is EV energy storage is DC, while most grids opperate on AC. So for energy to flow out, or into an EV storage system (battery) it needs to be converted. The conversion from AC-to-DC is built-in to all PEVs, but tends to be a low power (3-6 kW) to minimize weight in the vehicle. Conversion from DC-to-AC for grid specs requires a dedicated external inverter. (PEVs have an inverter to power the motor, but it was designed to ramp frequency and current based on speed and torque load … not to adjust current while supplying a constant grid-sync’d frequency)

      Types of V2G demonstrations:
      1. V2G Demand Loading: a controlled load applied to a grid to stabilize voltage at a remote part of a grid. For PEVs ths typically means controling the time and/or power level a PEV charges. ie: APEV consumes energy on demand, but does not supply energy to the grid. Demand Loadfing is something utilities pay for, particularly if you have a very large controllable load (eg: a fleet of PEVs)

      2. V2G :Energy Time Shifting using energy storage to move demand from a period of high cost (demand) to an off-peak period at lower costs. In this case, cheaper energy is stored, then used to supply part of local load when demand drives up price of power. Energy Time Shift can be used with solar power to provide energy beyond local daylight hours. This requires a battery to both source and store energy. PEV batteries that have reached ~70% of new capacity are economical in this case as energy density (kWh/kg) is a not a costraint for fixed location storage.

      3. V2G Capacity Firming: similar to Time Shifting in terms of hardware requirements, but smaller amounts of energy are shifted over shorter periods of time. The purpose is to balance supply capacity as energy use and sources vary dynamically throughout the day. Typically only 10-20% of energy storage capacity is used.

      4. Emergency Power Backup: not really a V2G role, but same V2G equipment use for Time Shfting can serve as a local energy source when a building has been disconnected from the grid.

      A. Level 2 capable PEV … can be used as part of a Demand Loading V2G component.
      B. EV-to-Home … eg: LEAF-to-Home (L2H) is both a DC charger and an AC power source. The L2H is a 6 kW system that integrates with a LEAFs ~20 kWh of usable energy.

        Well, Powerstream specifically says “the first commercial Vehicle-to-Grid (V2G) power supply system in North America with two high-capacity level 2 chargers connected to a solar carport”. The DC-to-AC conversion can happen either on the vehicle or off the vehicle, and there are plenty of examples of each through a number of demo projects, but saying “Level 2” suggests this unit relies on vehicles with on-board inverters, which in turn means they must have partnered with an automaker, or at least somebody capable of retrofitting an EV with a bidirectional onboard charger. Or they got mixed up in this statement, and the V2G equipment is separate from the Level 2 charging stations and in fact connects to a vehicle through a DC port.

        Regarding your example #1 – I’ve never heard any credible sources refer to controlled charging as V2G. While there’s a lot of variability in definitions of V2G (eg V2G vs V2H for example), it always consistently involves reverse power flow from the vehicle, regardless of whether it’s acting as a current source matching the grid frequency and voltage, or simply powering some isolated building or microgrid.

        Controlled charging is more generally refered to as “smart charging”.

        Thanks Brian H. for the definition of the High’Falutin’ terms.

        At least now I know what buzz words to use with the natives.

        Simple concepts apparently by the EV industry, cannot be left simple. Fine by me.

  2. Anon says:

    Is Tesla working on V2G?

    1. Tesla is not directly working on V2G technologies, but has a partnership with Solar City.

      Installing V2G equipment in a PEV does not make sense as it would never be used while on the road. And, the best time of day to use energy storage is typically when a PEV is likely to be away from home. Thus the use of dedicated residential storage makes more sense. (Post-PEV battery use is a possibility, but it will be 7-10 years before we see any significant quanity of used PEV packs.

      For commercial energy storage, the use of PEVs has a higher possibility, but developments in this area is limited … just the odd research/demonstration project.

  3. Ontario Leaf says:

    Power Stream is my power company.
    Great news, although my ’11 Leaf does not have the quick charging option I have friends who do.
    We need more of these units, currently there are only three in the Toronto area as far as I know.

    Community owned energy company? Please explain!

    Here’s where it’s located

      Not for you! That CCS-1 plug won’t fit your Volt.

  6. SmartElectric says:

    While PowerStream should be applauded for their deployment of a DC quick charger for city range

    electric cars like the BMW i3 and Nissan Leaf, the hardware itself has performed rather less reliably

    when compared to Tesla’s SuperCharger’s which are setting the speed and stability standard for the

    entire EV industry.

    See the plugshare comments for the new PowerStream charger for an example of the issues you can expect

    on technology that has not been well enough sorted out:

    You will note the Toronto Tesla SuperCharger has no such issues:

    I don’t own a Tesla, my car is a Smart ED, but I am well aware of the superiority of the Tesla efforts

    compared to the rest of the industry…
